At its outer end, clip 2 has a transverse endmember 5, which has theshape of a split cylinder, which has separated transverse edges Ea. Saidclip 2 has longitudinal and planar legs L, which are parallel to eachother and parallel to the straight longitudinal axis of helical spring6.

Said legs L have outer end-portions 4a and 3a which are transverselytapered, so that their wide edges are integral with edges 5a ofendmember 5. Said legs L have main body-portions 4 and 3 which arerectangular.

The inner ends of said legs L have integral flangeiwhich interfitsslidably andziturnablyiwith' 1949,1'Setia'iFNdi91480 2 Tlateral'e'xtensions '8 and l which'i ext'en'd in opposed lateraldirections.

40 Ir;it heextensions 8 andc'ltareipreferablyoriginally formed or shapedrelative to legs L, prior to forming or shaping the end-flanges 8 and I.When thus originally formed or shaped, each lateral extension 8 and Ihas surplus material for subsequently forming the end-flanges 8a. and1a.

When lateral extensions 8 and 1 are shaped prior to forming theend-flanges 8a and 1a, said junction lines E preferably follow thedesired helical contour. When the surplus material is then bent inwardlyalong junction lines E, to form end-flanges 8a and 1a, each saidend-flange 8a and la has the desired part-helical shape.

As shown in Fig. 3, the lateral extensions 8 and 1 are diametricallylaterally opposed, so that 3 their end-flanges 8a and 1a are alsodiametrically opposed.

Each end-flange 8a and la turnably and slidably engages substantiallyone-fourth of the circumference of a coil of helical spring 6.

In using this specific embodiment, the endfianges 8a and 1a are engagedwith one end of spring 6. The cross-bar I is extended through the hollowend-member 5. The clip 2 is turned relative to spring 6, until cross-barI is clamped between end-member 5 and the respective end of spring 6.

As shown in Fig. 2, the thickness of inner endwalls 8b and lb ispreferably greater than the normal longitudinal spacing of the coils ofspring 6. Hence, when clip 2 is assembled with spring 6, said spring 5is extended at inner end-walls 8b and lb and each inner end-wall 8b and1b is clamped and frictionally held between two adjacent coils of spring6.

The spring 6 may also thus frictionally clamp the lateral extensions 8and 1.

Each junction line E has the shape of a part of a helix which has thesame pitch as sprin 6, so that each junction line E has the same con;-tour as the coils of spring 6.

I have disclosed a preferred embodiment of my invention, but numerouschanges and omissions and additions can be made without departing fromits scope. sq

I claim:

1. A holding device, said device comprising a clip which has legs whichare spaced from each other, said legs being connected to each other atthe end of said clip, a helical spring assembled with said clip,'each ofsaid legs extending within the interior of. said spring and having afirst lateral offset which is located between adjacent first and. secondturns of said spring and which frictionally engages said respectiveadjacent turns of said spring and which has substantially the same pitchas said spring, each of said first lateral offsets having an extensionwhich is external to said spring and which is substantially parallel tothe axis of said spring and which has substantially the same pitch assaid spring and which has an inner convex wall which is adapted slidablyto receive said second turn of said spring and which is directed awayfrom the end of said clip, each of said extensions having a secondlateral offset which is located between said second turn of said springand an adjacent third turn of said pring and which frictionally engagessaid second and third turns of said spring and which has substantiallythe same pitch as said spring.

2. A holding device, said device comprising a clip which has legs spacedfrom each other and connected to each other at the end of said clip, ahelical spring assembled with said clip, the legs of said clip extendingpartially within the central hollow interior of said helical spring,said legs having respective lateral offsets which project indiametrically opposite directions, between adjacent turns of saidspring, said lateral offsets having sufiicient thickness to befrictionally engaged and compressed between the respective adjacentturns of said spring, each of said lateral offsets having an arcuate endextension located exteriorly of said spring and embracing a portion ofthe outer periphery of one of the adjacent spring turns, the free end ofeach said extension extending between said embraced spring turn and thenext adjacent turn and being compressed therebetween, said extensionshaving substantially the same pitch as said spring and being slidablearound the outer periphery of said spring, whereby said legs may bemoved longitudinally through the interior of said spring when said clipis rotated relative to said spring.

3. A holding device, said device comprising a clip which has legs spacedfrom each other and connected to each other at the end of said clip, ahelical spring assembled with said clip, the legs of said clip beingconnected at one end and being free at their other end, said legsextending within the central hollow interior of said helical spring andbeing axially aligned with said spring, each of said legs having aterminal lateral ofiset, said offsets extending substantiallyperpendicularly of said legs in opposite directions and between adjacentturns of said spring, said offsets having suflicient thickness to becompressed between the respective adjacent turns of said spring, each ofsaid ofisets having an arcuate end extension located exteriorly of saidspring and embracing a portion of the outer periphery of one of therespective adjacent spring turns, the free ends of each said extensionextending between said embraced spring turn and the next adjacent turnand being compressed therebetween, said extensions having substantiallythe same pitch as said spring and being slidable around the outerperiphery of said spring, whereby said legs may be moved axially throughthe interior of said spring when said clip is rotated relative to saidspring.
